1. I would say if she's otherwise healthy using an intraocular gas would be preferable to oil. However, positioning is really important to the success of the macular hole repair, so if she is unable to maintain this strict positioning requirement, go with the oil. Note that with the oil, a second surgery will be necessary to remove the oil.
2. No there are no other methods to repair a hole. Using laser or cryotherapy is not done because these procedures create scar tissue thus they would damage the macula even more.
3. With a stage three hole, the chances for improvement are very very slim, and surgery is almost always recommended. Without repair the odds are more likely that there will be further macular damage. Surgery, may not give her "normal" vision, but the goal of surgery is to try and preserve vision, and it may offer a line or two of improvement on reading the eye chart.
Dear roger397,
I would specifically ask her retinal specialist these questions.If you do not feel comfortable with the answers, seek a second opinion.
